In underground mine production，the underground water inflow is very important for mine safety，and to master the change law of water inflow and the influencing factors plays a vital role in the later mining process. Taking the water inflow of Zhongguan Iron Mine as the research object，the influence of sur⁃ face water level，water pressure and mine geological structure on mine water inflow is studied by field geo⁃ logical survey and regional hydrogeological numerical simulation. The results show that the changes of groundwater level and underground water inflow will be remained relatively stable and continued for a period of time without external supplement such as rainfall. The curtain has changed the water-rich and water-per⁃ meable properties of limestone，and reduced the water inflow of underground mines to a great extent com⁃ pared with natural aquifers，which provides strong support for ensuring safe production.
